TECHNICAL FIELD

The present invention relates to a complex-patterned wire net, which is mainly used for fences, and a method for manufacturing the same, and more particularly to a complex-patterned wire net, in which various-shaped holes are mixed to have various kinds, and a method for manufacturing the same.

BACKGROUND ART

In general, wire nets are mainly used for fences in stalls, factories, dams, military installations, water supply protection zones, etc., and are advantageous in that they sufficiently satisfy basic functions as fences, reduce a construction cost, and secure a field of vision through net holes.

Wire nets, which are being produced now, are three kinds, i.e., a tetragonal wire net, a pentagonal wire net, and a hexagonal wire net, which have different shapes of net holes. These wire nets are formed by continuously repeating the same-sized holes having any one shape, given according to kinds, in all directions. The shapes of the holes according to kinds are the same and the kinds of the wire nets according to the shapes of the holes are only three, thereby highly limiting consumer's choices. Particularly, wire nets having the same shape have been used for a long period without transformation of the shapes of net holes, and thus cause the deterioration of a design value, thereby being gradually disregarded by consumers. Accordingly, measures to cope with this problem have been urgently required in the art.

BEST MODE

Now, preferred embodiments of the present invention will be described in detail with reference to the annexed drawings.

In the drawings, the same or similar elements are denoted by the same reference numerals even though they are depicted in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIGS. 1 and 2 illustrate a complex-patterned wire net in accordance with one embodiment of the present invention. A complex-patterned wire net (A) in accordance with this embodiment is obtained by repeatedly forming a plurality of first net holes 100, forming a plurality of second net holes 200 under the first net holes 100, and then forming a plurality of first net holes 100 under the second net holes 200. The first net holes 100 are formed by twisting parts 110, 120, and 130, extensions 140, 150, and 160 formed by stretching longitudinal wires from the twisting parts 110, 120, and 130 to the right and left, and divisional transversal wires 170 and 180 crossing the twisting parts 110, 120, and 130, and the second net holes 200 are formed by twisting parts 210 twisted from the lowermost extensions 160 and several compartmental transversal wires 220 crossing the twisting parts 210.

Here, the twisting parts 110 located at the start point of the first net holes 110 are obtained by twisting two strands of longitudinal wires. Longitudinal wires are stretched from the twisting parts 110 to the right and left and are twisted with the neighboring longitudinal wires twice, the divisional transversal wire 170 is supplied among the longitudinal wires and then the longitudinal wires are twisted twice again, thus producing the twisting parts 120. Thereafter, longitudinal wires are stretched from the twisting parts 120 to the right and left and are twisted with the neighboring longitudinal wires twice, and the divisional transversal wire 180 is supplied among the longitudinal wires and then the longitudinal wires are twisted twice again, thus producing twisting parts 130. Thereby, the first net holes 100 each having a small regular square shape, which make a pair such that the divisional transversal wires 170 and 180 are interposed between the pairs of the first net holes 100, longitudinally alternate with one another.

When the twisting parts 110, 120, and 130 for forming the first net holes 100 are formed, the longitudinal wires of the twisting parts 110, 120, and 130 are twisted in the opposite directions among each other, and the longitudinal wires of the upper and lower portions of each of the twisting parts 110, 120, and 130 are twisted in the opposite directions with respect to the divisional transversal wires 170 and 180. Further, only in the case that the first net holes 100 are formed in an even number, it is possible to perform a continuous operation. When a wire net is manufactured using a wire net manufacturing apparatus, respective longitudinal wires are supplied from a feed unit, and pass through semicircular gears in a pair, which are rotated together at their positions or are rotated together with the rotation of a neighboring semicircular gear by a sliding operation, thus forming the twisting parts 110, 120, and 130, which longitudinally alternate with one another under the condition that the extensions 140, 150, and 160 are interposed between the twisting parts 110, 120, and 130. In this process, the semicircular gears cannot perform the sliding operation more than one column space from the viewpoint of its own structural characteristics. Further, since the semicircular gears provide the same twisting frequency of the longitudinal wires also to the feed unit at the rear of the semicircular gears when the longitudinal wires of the twisting parts 110, 120, and 130 are twisted by rotation, after the semicircular gears are rotated in any direction, the semicircular gears must be rotated in the other direction so as to perform twisting at the same frequency as that of the twisting parts 110, 120, and 130 such that transversal wires twisted at the feed unit cannot be twisted any more but can be untwisted at once so as to perform the continuous operation.

The first net holes 100 are completed by stretching longitudinal wires from the lowermost twisting parts 130 to the right and left and twisting the longitudinal wires with the neighboring longitudinal wires. Thereafter, the longitudinal wires are twisted four times, one divisional transversal wire 220 is supplied among the longitudinal wires, the longitudinal wires are twisted again four times, and then another divisional transversal wire 220 is supplied among the longitudinal wires. This procedure is repeated, thus producing the twisting parts 210. Thereby, the second rectangular net holes 200, each having a rectangular shape, which are divided by the compartmental transversal wires 220, are formed.

When the second net holes 200 are formed, the twisting parts 210 at a twisting start point are twisted in the opposite direction to the twisting direction of the lowermost twisting parts 130 of the first net holes 100, and the portions of the twisting parts 210 divided by the compartmental transversal wires 220 are twisted in the opposite directions with respect to the compartmental transversal wires 220. Further, only in the case that the second net holes 200 are formed in an even number, it is possible to perform a continuous operation without excessively twisting the longitudinal wires in any one direction.

Therefore, the first net holes 100 obtained by the present invention cannot vary in lateral width due to the intervals between the neighboring twisting parts 110, 120, and 130, but the first net holes 100, each having a small regular square shape are formed in zigzag by twice-twisting each of the upper and lower portions of the longitudinal wires of the twisting parts 110, 120, and 130 divided by the divisional transversal wires 170 and 180 between the extensions 140, 150, and 160. Further, the second net holes 200, each having a rectangular shape, which is vertically elongated, are formed under the first net holes 100 by four times-twisting each of the portions of the longitudinal wires of the twisting parts 210 divided by the compartmental transversal wires 220. Further, when the first net holes 100 and the second net holes 200 are respectively formed in even numbers, it is possible to perform the continuous operation regardless of the numbers of the first and second net holes 100 and 200. Thus, complex-patterned wire nets (A) of various kinds are obtained by varying the numbers of the first and second net holes 100 and 200, i.e., two first net holes 100 and two second net holes 200, two first net holes 100 and four second net holes 200, or four first net holes 100 and two second net holes 200.

FIGS. 4 and 5 illustrate a complex-patterned wire net in accordance with another embodiment of the present invention. In this embodiment, as shown in FIGS. 3 and 4, a complex-patterned wire net (B) having a new type is obtained by varying the twisting frequency of twisting parts 310, 320, and 330 to obtain first net holes 300 and the twisting frequency of twisting parts 410 to obtain second net holes 400.

That is, longitudinal wires of the twisting parts 310, 320, 330, and 410 of the first and second net holes 300 and 400 are twisted in the opposite directions and the first and second net holes 300 and 400 are respectively formed in even numbers so as to perform a continuous twisting operation. The longitudinal wires of upper and lower portions of the twisting parts 310, 320, and 330 divided with divisional transversal wires 370 and 380 are respectively twisted four times so as to form the first net holes 300, each having a rectangular shape, which is vertically elongated, and the longitudinal wires of portions of the twisting parts 410 divided with compartmental transversal wires 420 are respectively twisted twice so as to form the second net holes 400, each having a regular square shape.

Also, complex-patterned wire nets (B) of various kinds are obtained by varying the numbers of the first and second net holes 300 and 400, i.e., two first net holes 300 and two second net holes 400, two first net holes 300 and four second net holes 400, or four first net holes 300 and two second net holes 400.

FIG. 6 is a perspective view of a complex-patterned wire net in accordance with another embodiment of the present invention. In this embodiment, divisional transversal wires 570 and 580 of first net holes 500 and compartmental transversal wires 620 of second net holes 600 have a wave shape, in which protrusions and depressions are repeated.

That is, the transversal wires 570, 580, and 620 are supplied among longitudinal wires during twisting the longitudinal wires for forming twisting parts 510, 520, 530, and 610, and thus divide the respective net holes 500 and 600 from each other. In the case that the transversal wires 570, 580, and 620 have a wave shape, the transversal wires 570, 580, and 620 are more firmly bonded to the twisting parts 510, 520, 530, and 610, and thus enhance the strength of a wire net (C) and create a new aesthetic value of the wire net (C) while having the same sizes of the net holes 500 and 600.

FIG. 7 is a perspective view of a complex-patterned wire net in accordance with yet another embodiment of the present invention. In this embodiment, a twisted wire obtained by twisting two strands of wires is used as divisional transversal wires 770 and 780 of first net holes 700 and compartmental transversal wires 820 of second net holes 800.

The transversal wires 770, 780, and 820 using the twisted wire are more firmly bonded to twisting parts 710, 720, 730, and 810, and thus enhance the strength of a wire net (D) and create a new aesthetic value of the wire net (C) while having the same sizes of the net holes 700 and 800.

FIG. 3 is a schematic view of a complex-patterned wire net of the present invention, when the wire net is used as a fence. The complex-patterned wire net (A) of the present invention includes first and second net holes 100 and 200 having different sizes and shapes, and thus has a new aesthetic value and safety in appearance, thereby increasing in utility value.

INDUSTRIAL APPLICABILITY

As apparent from the above description, the present invention provides a complex-patterned wire net (A), in which net holes 100 and 200 having different sizes and shapes are arranged, and a method for manufacturing the same. Particularly, the first net holes 100 in an even number are formed in zigzag by twisting parts 110, 120, and 130, divisional transversal wires 170 and 180 crossing the twisting parts 110, 120, and 130, and extensions 140, 150, and 160, and the second net holes 200 in an even number are formed by twisting parts 210 twisted from the lowermost extensions 160 and several compartmental transversal wires 220 crossing the twisting parts 210 at proper intervals. Further, it is possible to obtain wire nets of various kinds having different overall shapes by varying the twisting frequencies of the twisting parts 110, 120, 130, and 210 and the numbers of the net holes 100 and 200, thus providing complex-patterned wire nets having new and various shapes and increasing the utility value of the wire nets.
